Selling my 2005 GMC Sierra 1500. The truck runs and drives great. I've driven back and forth from Pennsylvania three times and haven't had a problem since I bought it two years ago.

Specs:
Extended cab
L33 High output 5.3 V8 (has an aluminum block and 799 cylinder heads)
Push button 4 wheel drive transfer case with automatic mode
Z71 offroad package
Automatic transmission
Towing package with trailer brake controller
Rear has 4.11 gears and locking differential
Bedrug
Factory satellite radio and OnStar
236000 Miles

Work I've done since I bought it:
New Cooper Discoverer all terrain tires
New front O2 sensors
New alternator
Fixed pump rub in transfer case
Replaced differential and transmission fluid
Replaced a couple universal joints
Replaced the factory muffler with a Thrush Welded muffler (similar to Flowmaster 40 series)
Replaced dashboard lights with blue leds (the lower steering wheel controls still need done but I never got around to them)
